1. 36. Validering av KFX för vätgasjetflammor som träffar ytor

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Jonathan Nilsson; [2024]
   Nyckelord :Kameleon FireEX; KFX; CFD; Hydrogen Jetfire; Technology and Engineering;

   Sammanfattning : Regarding climate change and the future need för renewable energy, hydrogen is considered to be an important component in energy storage systems. However, the use of hydrogen is fraught with risk due to its chemical properties. This thesis deals with the problem of modelling heat transfer from hydrogen jet flames hitting surfaces. LÄS MER

5. 39. Exploring Urban Land Cover Changes and the Effect on Nocturnal Air Temperature Dynamics in Helsingborg - A temperature modeling made with TAPM

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Amanda Bäck; [2023-10-09]
   Nyckelord :Nocturnal Air Temperature; Intra-Urban Heat Island; Land Cover Classification; Deep learning; The Air Pollution Model TAPM ; Land Cover Change;

   Sammanfattning : In light of increasing global temperatures, urban areas face growing challenges related to heat stress. Alterations in land cover (LC) within cities contribute to changes in the intra-urban climate, predominantly driven by the replacement of vegetated surfaces with impermeable materials. LÄS MER

7. 40. APPLICATION OF IN SITU Rb-Sr DATING AND GEOCHEMICAL INVESTIGATIONS ON A NEW, 1.52-1.56 GA. OLD PEGMATITE FIELD IN THE ARCHIPELAGO OFF GOTHENBURG, IDEFJORDEN TERRANE, WESTERN SWEDEN

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Laszlo Zorc; [2023-08-18]
   Nyckelord :;

   Sammanfattning : In this study, Rb-Sr geochronology was used to determine the crystallization/cooling ages of muscovites and biotites from mapped primitive barren and rare element pegmatites in the Stora-Le-Marstrand Formation in the southwestern archipelago of Gothenburg. The results indicate that primitive barrens can be linked to the DG2 deformation event that occurred 1. LÄS MER
